Class PredicateParser

Parser that can build a predicate from a string representation. The underlying syntax is quite simple, and example is shown below:

path["/MyPath"] or (method[value="POST"] and not headersPresent[value={Content-Type, "Content-Encoding"}, ignoreTrailer=true]

The following boolean operators are built in, listed in order or precedence: - not - and - or

They work pretty much as you would expect them to. All other tokens are taken to be predicate names. If the predicate does not require any parameters then the brackets can be omitted, otherwise they are mandatory.

If a predicate is only being passed a single parameter then the parameter name can be omitted. Strings can be enclosed in optional double or single quotations marks, and quotation marks can be escaped using \".
